CULINARY VESSEL.

SPECIFICATION forming part of Letters Patent No. 710,681, dated October'7, 1902.

Application filed April 24, 1902. Serial No. 104,460- No model.)

1'0 It whom it may concern: I 1

Be it known that I, CHARLES GRoTHE, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented new and useful Improvements in Culinary Vessels, of whichthe following is a specification.

My invention relates to a culinary vessel adapted to drain the contentsof the same without removing the lid, the object of the invention beingthe prevention of the escape of the steam at the top rim of the lidduring the draining operation, excepting at the place of drainage, meansfor discharging the water that may enter the rim, and means fortightening the members of the lid.

To this end the invention consists of details of construction which willbe hereinafter described and the novel features pointed out in claims.

Figure 1 represents a vertical section of a portion of a culinary vesselembodying my invention. Figs. 2 and 3 represent top or plan viewsthereof. Fig. l represents a vertical section of a portion on line :11ac, Fig. 2. Fig. 5 represents a vertical section of a portion on line yy, Fig. 2, omitting the upper member of the lid of the vessel.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a portion of the body of aculinary vessel of the order of a domestic boiler orsteamer, and Bdesignates the lid thereof. The lid has two top walls, the lower wall 0,which is connected with the rim D of the lid and having therein in oneportion of the same aseries of openings or open-work, as at E, theremaining portion F being solid. The upper wall G rests rotatively onthe inner wall 0 and is solid excepting at the portion H, where it iscut away, forming an opening J, which at proper times uncovers theopenings E.

In order to connect the walls 0 and G, I employ the screw K, which ispassed freely through the centers of the same and has on its outer endthe knob L as a shoulder and handle and on its inner end the nut M, bywhich provision said walls may be adjustably tightened on each other,and an axis is provided for the upper wall G. As said screw passesfreely through the centers of the walls 0 and G, it will be noticed thatthe rotation of the upper wall G is not accomplished by the operation ofthe knob L, but by that of the thumb or finger piece L on said plate, bywhich provision the adjustment of the friction or closeness of thejoint. between said walls is not disturbed.

N designates a circular flange which is secured to the inner peripheryof the rim D and projects inwardly therefrom, so as to circumscribe theperipheral portion of the upper or outer walls and overhanging the outeredge of said wall, thus retaining the peripheral portion of said wall Gclose to the adjacent portion of the inner wall and covering the jointbetween the two walls The flange is cut away at places P and Q adjacentto the openings E in the inner wall 0 for purposes to be hereinafterexplained. Said flange,however, is continuous excepting at said places Pand Q.

The operation is as follows: During steaming or cooking of the articlewithin the body A the wall G is turned so as to cover the openings E,thus retaining the steam and heat within said body. \Vhen it is desiredto drain the vessel, the wall G is turned from the position shown inFig. 3to that shown in Fig. 2, whereby the openings E are uncovered.Then the vessel maybe tilted or overturned and the water in the bodypoured out through the openings E. Owing 10 the circumscribing nature ofthe flange N over the peripheral portion of the wall G steam and heatare prevented from directly escaping at the joint between the two wallsand scalding or burning the holder of the vessel. In the tilted oroverturned condition of the vessel Water may enter the flange N betweenthe openings P and Q, in which case by properly turning the vesselsidewise said water may escape through either of said openings P Q as apour-01f. It is evident that during the cooking or steaming operationshould there be an excess of steam or heat within the vessel the samemay be relieved by uncovering the openings E. When the nut M is removed,the screw K may be withdrawn, thus releasing the top wall or plate G, sothat the latter may be raised clear of the plate C, and both plates arein condition to be cleansed, especially where their faces have beencontiguous.

Various changes may be made in the details of construction withoutdeparting from the general spirit of my invention, and I do not desire,therefore, to be limited in each case to the same. I

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a culinary vessel, a lid having its top formed of two walls, onewall being partly solid and partly perforated, and the other wall partlysolid and partly cutaway, and a flange on the lower wall, said flangebeing continued inwardly from the periphery of said lower wall andoverhanging the peripheral portion of the upper wall.

2. In a culinary vessel, a lid having a top formed of two members, thelower one of which is stationarily connected with the rim of said lidand the upper one is rotatable on said stationary wall, each of saidwalls being partly solid and partly perforated, a thumbpiece on therotatable wall, and a screw which is passed freely through the centersof the two walls and means for tightening said walls on said screw, saidscrew forming the axis of the rotatable wall without capability ofturning the same.

3. In a culinary vessel, a lid formed of a rim, a stationary wallconnected therewith and a rotatable wall above said. stationary wall,both walls being partly solid and partly open and a flange extendinginwardly from said rim and overhanging the peripheral portion of theupper wall and covering the joint of the two walls, said flange having apourotf opening therein.
